Today, video surveillance, access control and other related security systems are deployed across organizations of all types and sizes. For some, the systems serve a conventional purpose to help defend against theft, vandalism and other unlawful acts while others may extend their use to complement business operations such as liability management, process management, human resource operations, inventory control and integration with POS (Point of Sale) terminals. Whatever the specific application, these systems have become an integral part of the client operation and as such must be maintained in peak operating condition.
